The project epZilla was initiated with the aims to create a scalable fault tolerant architecture for complex event processing systems. At the end of the allocated time period, we have looked back at the Distributed System Architecture which we came up after a successful research effort on both Distributed Systems and Complex Event Processing domains.

The weights of our research are nearly 70% on Distributed Systems domian and 30% on Complex Event Processing domain. As a result, we were able to design a sophisticated Distributed Systems Architecture for Complex Event Processing Systems. As this system is sophisticated for Complex Event Processing Systems, it poses some of the Complex Event Proceesing system features such as Stratification. This idea is introduced by several IBM researchers recently and therefore it is fairly new idea for Complex Evet Processing domain as well. Therefore we believe project epZilla might be the first practical implementation of the Stratification.

Since project epZilla is a research project, we implemented a prototype implementation of the Distributed System Architecture which we designed to validate the design and the performance measures. Therefore we have implemented all the components introduced in the design with several value added features such as dynamic load balancing and integrated them and drove lot of test runs with several physical nodes and measured the performance of the system. These performance information confirmed the correctness of our design and achievement of our design motivations such as high throughput while preserving Fault Tolerance and Scalability of the system. Therefore we have successfully demonstrated our research effort, Project epZilla to our Academic Staff of the Department of Computer Science & Engineering, University of Moratuwa, Sri Lanka using the prototype implementation of the design and explained why such design decisions were made and how those designs were practically implemented.

At the end, we have designed and developed a Scalable Fault Tolerant Distributed Architecture for Complex Event Processing Systems. We are proud and delighted to annouce that we are concluding this research project with a great success of 100% achievment of the project goals.

The final Project presentation of project epzilla was done on the 23rd June 2010. The final demonstration was done on the 24th of June 2010. With the successful completion of the presentation and demo, the research and development components of the project came to a conclusion. The completion of the documentation, which includes user manuals, final report and four separate research papers still has to be done.

Now we have started the implementation of the components of our proposed architecture. Dispatcher, Leader Election, Accumulator, Node implementations as well as STM implementation for all the above components are being developed by four of us. We wish to completed 70% of the implementation by 10th March 2010.

Currently over 80% is completed in each and every component of the project including Dispatcher, Leader Election, Accumulator and STM for them. So now it is about the System Integration and Testing. We are planning to start testing on individual components by Monday 8th March and integrate the System and conduct testing on the integrated components on 9th and complete the rest of the work by 10th March.

We have our 3rd formal evaluation and Demo on 11th and 12th March 2010. We are planning to face it strongly and succeed.

Since we have completed the implementation of our projects web site on September, we could not able to work on it lately. However with a small free time period which we got, we have launched our web site at http://www.epzilla.net. We are planning to keep it up to date as much as possible. Please feel free to have a look at it make a comment. We highly value your comments.
